Social support and managing schizophrenia in Tanzania: Perspectives from treatment-engaged individuals and relative caregivers.

Background: In lower-resource settings like Tanzania, people living with schizophrenia (PWS) rely on their families for much of their social support, thus leading family members to become their main caregivers. How PWS and their families understand and implement social support can profoundly impact recovery pathways. This study examines how PWS and caregivers of PWS in Tanzania describe receiving and giving social support. We describe, from the perspectives of treatment engaged PWS and unmatched caregivers, different types of social support experienced and provided and examine any differences in the types and expectations of social support expressed by PWS versus caregivers. Methods: A total of 39 semi-structured in-depth interviews were conducted with PWS (n = 19) and caregivers (n = 20) recruited from outpatient psychiatric clinics in tertiary-level hospitals in Tanzania across two geographic regions. Thematic content analyses were based on four dimensions of social support (instrumental, emotional, informational, and appraisal). Results: Results revealed four themes: 1) Financial and basic needs support from families is common yet critical for daily living (instrumental support); 2) There were mixed experiences regarding provision and receipt of love and acceptance with desires and calls for more encouragement and moral support (emotional support); 3) Caregivers try to provide knowledge, guidance, and reminders related to illness management for PWS but acknowledge their own gaps in understanding recovery promotion and effective caregiving (informational & appraisal supports), 4) A cross-cutting issue was calls for more social support from the wider community. Conclusion: Social support is a multi-dimensional construct recognized by PWS and caregivers as critical for illness management, yet gaps remain, often due to lack of knowledge of how to bolster social support. Given the heavy reliance on families for social support in lower-resource contexts, psychiatric services can intervene with clinic-based psychoeducation for PWS and their families to improve quality of life and functioning.

Functioning and quality of life among treatment-engaged adults with psychotic disorders in urban Tanzania: Baseline results from the KUPAA clinical trial.

BACKGROUND: There is a treatment gap for those living with severe mental illnesses in low- and middle-income countries, yet not enough is known about those who are currently accessing clinical services. A better understanding of potentially modifiable factors associated with functioning and quality of life will help inform policies and programming. AIMS: To describe the functioning and quality of life for a psychiatric treatment-engaged population living with psychotic disorders in two urban areas of Tanzania, and to explore their respective correlates. METHODS: This study analyzed cross-sectional data from 66 individuals enrolled in the Kuwezeshana Kupata Uzima (KUPAA) pilot clinical trial who had a diagnosis of schizophrenia or schizoaffective disorder, recent relapse, and who were receiving outpatient treatment. Baseline functioning (WHO Disability Assessment Schedule 2.0) and quality of life (WHO Quality of Life BREF scale) were measured. Univariable and multivariable regression analyses were conducted to determine correlates of functioning and quality of life. RESULTS: Adjusted analyses indicated that higher disability was associated with higher food insecurity, more symptomatology, more self-stigma, less instrumental support, less hope, lower self-efficacy, and/or lower levels of family functioning. Higher quality of life was associated with higher levels of self-efficacy, more hopefulness, more instrumental support, less self-stigma, and better family functioning. CONCLUSIONS: Identification of factors associated with disability and quality of life can help clinicians and policymakers, as well as consumers of mental health services, to better co-design and target psychosocial interventions to optimize their impact in low-resource settings.

Palaeontological evidence for an Oligocene divergence between Old World monkeys and apes.

Apes and Old World monkeys are prominent components of modern African and Asian ecosystems, yet the earliest phases of their evolutionary history have remained largely undocumented. The absence of crown catarrhine fossils older than ∼20 million years (Myr) has stood in stark contrast to molecular divergence estimates of ∼25-30 Myr for the split between Cercopithecoidea (Old World monkeys) and Hominoidea (apes), implying long ghost lineages for both clades. Here we describe the oldest known fossil 'ape', represented by a partial mandible preserving dental features that place it with 'nyanzapithecine' stem hominoids. Additionally, we report the oldest stem member of the Old World monkey clade, represented by a lower third molar. Both specimens were recovered from a precisely dated 25.2-Myr-old stratum in the Rukwa Rift, a segment of the western branch of the East African Rift in Tanzania. These finds extend the fossil record of apes and Old World monkeys well into the Oligocene epoch of Africa, suggesting a possible link between diversification of crown catarrhines and changes in the African landscape brought about by previously unrecognized tectonic activity in the East African rift system.
